Claims. Cl. 21146) This invention relates to slides and morespecifically horizontal pivot slides.

Broadly, it is an object of the invention to provide a slide which canbe attached to a horizontal member to provide a means for hanging andstoring articles, such as samples, permitting such articles to be pulledoutwardly for display purposes.

More specifically, it is an object of the invention to provide a meansfor storing and hanging materials, such as rug and fabric samples fordisplay purposes so that a salesman can easily pull out the rug orsample he wishes to display and then swing the rug or sample around toany desired position for examination by the customer.

A further object of the invention is to provide a rotatable andextensible slide for a storage and display cabinet in which articles,samples and inventory of certain types may be stored and easilydisplayed to advantage when desired.

For a fuller understanding of the nature and objects of the invention,reference is had to the following detailed description, in connectionwith the accompanying drawings, in which:

Fig. 1 is a perspective view of a storage cabinet partly broken away,showing several slides of a bank of slides holding two rug samples (asone example of use) back to back, with the pivot channel of the slideextended and rotated 90.

Fig. 2 is an enlarged perspective view of the horizontal pivot slide,partly broken away, showing the pivot channel in dotted positionparallel to the slide so that the track and channel may be retracted.

Fig. 3 is a side view of the pivot slide in retracted position.

Fig. 4 is a side view of the pivot slide in partially extended position,parts being broken away to show details of construction.

Fig. 5 is an end view of the pivot slide without any goods being heldwithin the pivot channel.

Referring to the drawings, numeral represents a pivot slide comprising achannel 11, which may be fastened by screws through screw holes 37 undera horizontal shelf or top member 12 of a storage cabinet 13 (shown inFig. 1), a center track 14 and a pivot channel 15. Between the channel11 and the center track 14 there is a U-shaped ball spacer 16 containingentrapped ball bearings 17 to provide easy rolling of the center track14. T he pivot channel is attached at its central point to the end ofthe center track 14 by means of a flat head master screw 18 having awasher 19 and an elastic stop nut 29 at its lower end, permitting thechannel 15 to rotate. Pivot channel 15, however, is prevented fromrotating by means of the ball 21 and spring 22 recessed in center track14 which maintains a constant pressure upon the ball 21. A set screwretains the ball 21 and spring 22 within the retaining hole 23. The ball21 projects out of its retaining hole 23 and into a corresponding hole24 in the pivot channel 15. The ball 21 prevents the pivot channel 15from rotating away from a position parallel to the channel 11 until asuflicient rotating force on the pivot channel 15 cams the ball 21 upand allows the pivot channel 15 to rotate.

The pivot channel 15 has two holes 24, 26, each spaced apart from themaster screw 18 the same distance as set screw 25 so that the ball 21will fall into holes 24 or 26, and retain the pivot channel 15 inparallel position with the slide or channel 11 every so that the pivotchannel 15 is in position for sliding back into the cabinet 13. It willbe seen that the pivot channel 15 can rotate 360 and is retained inparallel relation to the slide 10 by means of the ball 21 and spring 22.

Pivot channel 15 has a series of grip plates 28 which have tapped holesand are operated by Allen head cap screws 29 which act as lead screwsfor moving the plates 28 transversely of the pivot channel 15. One ortwo materials, such as rug samples 30, shown back to back, are passedinto the pivot channel 15 and are gripped and retained therein by amultiplicity of grip plates 28, three of which are shown herein forillustrative purposes only, since any number may be used depending uponthe type and weight of the article to be gripped. The grip plates 28press the articles 30' against the edge 33 of the inner flange of thepivot channel 15 to retain it against displacement.

After the article or articles, such as the rug samples 30 shown, arethus gripped and retained within the pivot channel 15, the slide may beextended and the pivot channel 15 may be pivoted360 to display bothfaces of the rug samples 30.

The center track 14 is prevented from leaving the channel 11 since therear locking pin 34, which passes through a transverse hole adjacent therear end of the center track 14 abuts the rear end of the U-shaped ballspacer 16. The front end of the ball spacer 16 abuts the extruded stop31 when the pivot channel 15 and center track 14 are extended thuspreventing the channel 15 and center track 14 from leaving the slide 10.In the positions shown in Figs. 3 and 4, the lock pins 34 and 36 strikethe ball spacer 16 at approximately the same instant that the ballspacer 16 strikes the extruded stops 31, 35 of the channel 11 in theretracted and extended positions. When the pivot channel 15 and centertrack 14 are retracted, the rear end of the ball spacer 16 abuts therear extruded stop 35 and the front locking pin 36 abuts the front edgeof the U-shaped .ball spacer 16 preventing the inner end of the centertrack 14 from striking the rear of the storage cabinet 13. The travel ofthe ball spacer 16 equals half of the total travel of the track 14 andin the intermediate posi tion, that is when the track 14 has completedone half of the total travel from front to rear and vice versa, the ballspacer 16 is positioned halfway between the stops 31, 35.

In assembling the slide, the stop 31 or stop 35 is extruded only, theslide is then assembled with the ball spacer 16 and then the other stop31 or 35 is extruded to retain the parts together.

When the pivot channel 15 is slid into the cabinet 13 the end of thepivot channel 15 should be flush with the end of channel 11, as shown inFigs. 1 and 3.

It is obvious that the grip plates 28 and the inner ends of the pivotchannel may be formed dilferently than shown, as for example, a seriesof pointed members for gripping fabric samples, or plates 28 may beextended below the inwardly directed flanges of the pivot channel topermit various attachments to be added, such as bolts, etc. forattaching other articles or samples, such as various kinds of wood,plastic, or compositions primarily used for display samples.

It is also obvious that various changes may be made in the details ofconstruction and arrangement of parts without departing from the generalspiritofithe invention.
